. Application filed March 24, 1917. Serial No. 157,272.

(GRANTED UNDER THE PROVISIONS OF THE ACT OF MARCH 3, 15221, 41 STAT. L, 1313.)

To all whom it may concern:

Be it known that l, Orro STAVENHAGEN, chartered accountant, a subject of the King of Prussia, German Empire, and residing at Charlottenburg, near Berlin, Germany, have invented certain new and useful Improvements in Letter 'Files or Registrators, of which the following is a specification.

The well-known letter files, registers, por folios and the like have usually the form of a book cover with a narrow back part and two side parts of equal form, fastened to the middle back part. Insideof this letter file in the form of a book cover there is provided a suitable device for mounting or filing the papers to be kept in good order. This device comprises a bent piece or how having two parts one of which is adapted to be opened in order to file the papers (punched correspondingly) on the bow, or to keep the papers in good order by drawing some of the papers onto that part of the bow capable of being swung outwardly so that letters or papers inserted at a prior filing can be drawn out, or be read or other papers can be inserted between such letters or papers stored previously without being forced to lift the entire mass of letters or papers from the letter file. In order to attain these advantages the bow must be comparatively high, so that even if the letter file is completely filled the bow rises considerably above the registered papers. Of course the papers can be filed only over the fixed but smaller part of the bow, because otherwise they would fall ofi in. disorder if the bow is opened. With this small fixed part of the bow the other part. bent semicircularly and adapted to be rocked or swung outwardly, is arranged to cooperate and this bent part and determines the width of the back part of the letter file. So it follows that the width of this back part is much larger than would be necessary to receive the entire pile of papers to be inserted in the letter file. Consequently the well known letter files are always in transverse section wedge shaped if they are empty as well as when they are partly or completely filled, wherein the back part of the letter file is the back of the wedge and the two parts of the cover joining each other with their edges form the edge or bit of the wedge.

These well known wedge-shaped letter files have the drawback that they require a-large space as compared with the pile of papers to be stored in each letter file. If they are assembled in book cases, stands or the like, a large space is taken up by the large back part of the'letter files. This drawback will be noticed especially in large register-ofiices or registries. Furthermore these letter files rateatedrrayaieea T tilt over very easily and require therefore separate covers or the like in order toset them inbook cases, stands or thelike.

The present invention w1ll overcome these drawbacks; for instance it will do away with i the great loss of space now unavoidable in storing the well-known letter files in that the space now lost will be filled by a second letter file being adjusted with its back part to one side part or cover of the usual letter file in such a manner that the side part or side cover common to both letter files will bear on each side symmetrically to each other, a separate filing bow with its usual accessories. In this manner the wedge shaped letter file, by attaching a second letter file receives a rectangular transverse section; the smaller sides of this rectangular form constitute the back parts of the two letter files arranged on opposite sides to each other.

In the drawing the invention is shown diagrammatically in cross section.

The present letter file consists of a middle part 9 bearing on each side symmetrically a separate filing how I) of well known, suitable construction with its usual accessories. On each end of this middle part 9 is fastened a separate back part r r of a known letter file and these back parts 1" r are joined on the other side with a separate cover d (Z respectively adapted to close the letter file. Therefore the new letter file has a rectangular cross section, whereas the known letter files have a triangular cross section. The formerly useless space required by the back. part or by the bow of the letter file in setting the same in a book case or stand is filled up by a second letter file and the complete letter file stands firmly without a separate cover or case. 7

Furthermore this new letter file is cheaper to manufacture and does away with the covers now required. The letter file can be made of any suitabe material and its different parts may be joined and adjusted in any suitable manner. If required the complete letter file can be in one piece.

The invention is adapted for any suitable form of letter files, binders, or the like.

I claim:

1. The combination with a letter file or portfolio having the form of a book cover and containing inside a device for filing or assembling the papers to be stored in the letter file, of a second filing device attached to the one side part of the first letter file and opening in the opposite direction to the latter.

2. The combination with a letter file or portfolio having the form of a book cover bearing on one side part or cover a device for filing or assembling the papers to be stored, of a second device for filing or assembling the papers on the other side of such side part of the letter file and arranged symmetrically to the first assembling device, a second back part of a letter file attached to that side part of the first letter file and a third side part of a letter file attached to the second back part.

3. A portfolio comprising a support, a

filing device mounted on one side thereof ad- I,

jacent one end, a filing device mounted on the other side of the support at the end opposite the other device, and covers connected with the support at'opposite ends and sides thereof. b

5. A portfolio comprising an inner supporting member, a filing bow on one side of said member adjacent one end thereof, a back portion connected to the supporting member near said bow, a cover connected to the back portion and extending over the loop and supporting member, and a loop, back, and cover connected to t e support at the opposite end and side thereof.

In testimony whereof I have afiixed my signature in the presence of two witnesses.
